LIU-ION LEIR dump 21/8/2014 – D.Manglunki

A new LEIR dump?

Pb beams prepared by LEIR for the LHC are lost in LEIR machine when undesired by the LHC (Extraction kickers inhibited)Pb beams prepared by LEIR for MDs are extracted towards the PS and lost on the PS septumBoth cases have detrimental effects on the vacuum of the machinesIt would make sense to cleanly dump those beams, especially in view of the higher intensity foreseen for after LS2.Pb54+ beams, 72MeV/nucleon, 2x109 ions every 3.6 secondsH=6mm ; sH=4mm

Other species before LS2 only:

− Ar11+ beams, 81MeV/nucleon, 3x109 ions every 2.4 second

− Xe54+ beams, 97MeV/nucleon, ?x109 ??? ions every 2.4 second

Similar dump has been studied earlier for a different case but same beam specifications Installation during LS2 (earlier is welcome if EN/STI has resources)Budget? Manpower? Timeline?

Principle of dump

Pb beams prepared by LEIR will always be extractedIf PS or LHC not ready ETL.BHN10 inhibitedDump at end of “Y” vacuum chamber for beam going straight
